What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 8 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (1,140 mg) without saying how much of each component you get.

Li Dan Pian contains 8 ingredients total. The active ingredients include Baikal Skullcap (Scutellaria baicalensis), Rhubarb root (Rheum palmatum), Elecampane (Inula helenium), Honeysuckle (Lonicera japonica), Bupleurum (Bupleurum chinense), Isatis (Isatis indigotica), and two ingredients we cannot fully evaluate: Lysimachia christinae and Artemisia capillaris.

The product also contains several inactive ingredients — Microcrystalline Cellulose, Dextrin, Hypromellose, Polyethylene Glycol, and Magnesium Stearate — which serve as binders and fillers.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Menopausal symptoms — rated "Possibly Effective" (Rhubarb) (Natural Medicines).
  • On file: Pancreatitis — rated "Possibly Effective" (Rhubarb) (Natural Medicines).
  • On file: Psoriasis — rated "Possibly Effective" (Isatis) (Natural Medicines).

The evidence we hold on these ingredients doesn't establish strong effectiveness for any condition. Rhubarb shows possibly effective ratings for pancreatitis and menopausal symptoms.

Isatis shows a possibly effective rating for psoriasis. The remaining ingredients — Baikal Skullcap, Elecampane, Honeysuckle, Bupleurum, and the two ingredients we cannot check — either have insufficient reliable evidence or no established ratings in our data for their traditional uses in this formula.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 6 of the 7 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 7.
  • General safety write-ups exist for 7 of 7.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Orally, Baikal Skullcap and Rhubarb seem generally well tolerated, though adverse effects are possible. Baikal Skullcap may cause abdominal pain, constipation, diarrhea, nausea, or vomiting; rare serious effects include liver damage and a lung condition called hypersensitivity pneumonitis.

Rhubarb commonly causes cramping, diarrhea, nausea, or vomiting, and chronic use can deplete potassium and affect the kidneys. Elecampane can trigger allergic contact dermatitis and cause stomach upset.

Honeysuckle is generally used as a tea with few reported problems, though allergic reactions have been documented. During pregnancy, safety data are insufficient or advise against use for Baikal Skullcap, Rhubarb, Elecampane, Bupleurum, Honeysuckle, and Isatis.

Rhubarb is rated possibly unsafe in pregnancy. For breastfeeding, safety data are inadequate for all ingredients; avoid medicinal use while nursing.

Talk with your doctor or pharmacist if you're pregnant or breastfeeding.

For each ingredient in Li Dan Pian with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Scutellaria baicalensis12 drug types · 946 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, Baikal skullcap might increase the risk of bleeding when used concomitantly with anticoagulant and antiplatelet drugs.
Preliminary clinical research suggests that taking capsules containing a combination of astragalus, goldthread, and Baikal skullcap daily for 4 weeks inhibits platelet aggregation; the effect seems to be similar to that of aspirin 50 mg daily. It is unclear if this effect is due to Baikal skullcap, other ingredients, or the combination.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of Baikal skullcap with antidiabetes drugs might enhance blood glucose lowering effects.
Baicalein, a constituent of Baikal skullcap, has alpha-glucosidase inhibitory activity in vitro. Animal research also suggests that Baikal skullcap enhances the antidiabetic effects of metformin. However, in a small human study, taking Baikal skullcap extract did not enhance the antidiabetic effects of metformin, although it did modestly lower glucose levels during an oral glucose tolerance test (OGTT). Until more is known, use cautiously.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, concomitant use of Baikal skullcap with antihypertensive drugs might have additive effects and increase the risk of hypotension.
Animal research suggests that baicalein, a constituent of Baikal skullcap, might lower blood pressure.

Likelihood Possible Evidence D
Antithyroid Drugs

Theoretically, concomitant use of Baikal skullcap and antithyroid drugs may result in additive activity and increase the risk of hypothyroidism.
In an animal hyperthyroid model, Baikal skullcap improved levels of triiodothyronine (T3), thyroxine (T4), and thyroid stimulating hormone (TSH). The clinical significance of this effect is unclear.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, Baikal skullcap may increase levels of drugs metabolized by CYP1A2 enzymes.
In vitro evidence suggests that constituents of Baikal skullcap inhibit the activity of CYP1A2. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, Baikal skullcap might increase levels of drugs metabolized by CYP2C19 enzymes.
In vitro evidence suggest that wogonin, a constituent of Baikal skullcap, modestly inhibits the activity of CYP2C19 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, concomitant use of large amounts of Baikal skullcap might interfere with hormone replacement therapy, due to competition for estrogen receptors.
In vitro evidence suggests that Baikal skullcap has estrogenic activity.

Likelihood Possible Evidence D
Lithium

Theoretically, Baikal skullcap might reduce lithium excretion and increase serum levels of lithium.
Baikal skullcap is thought to have diuretic properties, which may reduce lithium excretion. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Alcohol (Ethanol)

Theoretically, Baikal skullcap might potentiate the sedative effects of alcohol.
In vitro and animal research suggests that Baikal skullcap binds to GABA-A receptors and causes sedation. Theoretically, Baikal skullcap might potentiate the sedative effects of alcohol. Preliminary clinical research has not identified clinically relevant sedation after use of Baikal skullcap; however, a thorough evaluation of safety outcomes has not been conducted.

Likelihood Unlikely Evidence D
Cns Depressants

Theoretically, Baikal skullcap might cause additive therapeutic and adverse effects when used concomitantly with drugs with sedative properties.
In vitro and animal research suggests that Baikal skullcap binds to GABA-A receptors and causes sedation. Theoretically, Baikal skullcap might cause additive therapeutic and adverse effects when used concomitantly with drugs with sedative properties. Preliminary clinical research has not identified clinically relevant sedation after use of Baikal skullcap; however, a thorough evaluation of safety outcomes has not been conducted.

Likelihood Unlikely Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Theoretically, Baikal skullcap might alter the levels and clinical effects of OATP substrates.
Some pharmacokinetic research shows that baicalin, a constituent of Baikal skullcap, can decrease plasma levels of rosuvastatin. The mechanism is thought to involve stimulation of the activity of the organic anion-transporting polypeptide 1B1 (OATP1B1), which transports rosuvastatin into the liver. This decreases plasma levels of the drug, but increases levels at the site of action in the liver. The degree to which rosuvastatin levels are affected depends on the OATP1B1 haplotype of the individual. Baikal skullcap might also affect other OATP1B1 substrates.

Likelihood Possible Evidence B
P-Glycoprotein Substrates

Theoretically, Baikal skullcap might increase levels of drugs transported by P-glycoprotein.
In vitro and animal research suggests that baicalein, oroxylin A, and wogonin, constituents of Baikal skullcap, can inhibit P-glycoprotein. This effect has not been reported in humans.

Likelihood Possible Evidence D
Scutellaria baicalensis full monograph & interactions

Rheum palmatum8 drug types · 658 drugs

Corticosteroids

Theoretically, frequent and high doses of rhubarb might increase the risk of hypokalemia when taken with corticosteroids.
Rhubarb has stimulant laxative effects. Overuse of rhubarb might compound corticosteroid-induced potassium loss.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, taking rhubarb with cyclosporine might reduce cyclosporine levels.
Animal research shows that co-administration of rhubarb decoction 0.25 or 1 gram/kg with cyclosporine 2.5 mg/kg, decreases cyclosporine maximum plasma concentration and overall exposure levels when compared with taking cyclosporine alone. The authors theorize that rhubarb might reduce cyclosporine bioavailability by inducing of P-glycoprotein and/or cytochrome P450 3A4. However, since rhubarb was administered as a single oral dose and enzyme induction usually occurs after multiple doses, it is possible that cyclosporine absorption was actually reduced via rhubarb's stimulant laxative effects. Also, the composition of the rhubarb decoction was not described.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, overuse of rhubarb might increase the risk of adverse effects when taken with digoxin.
Rhubarb has stimulant laxative effects. Overuse of rhubarb might cause potassium depletion, increasing the risk of digoxin toxicity.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, frequent and high doses of rhubarb might increase the risk of hypokalemia.
Rhubarb has stimulant laxative effects. Overuse of rhubarb might cause potassium depletion and compound diuretic-induced potassium loss.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, concomitant use of rhubarb with potentially hepatotoxic drugs might increase the risk of developing liver damage.
Some animal research suggests that anthraquinones in rhubarb might have hepatotoxic effects. Also, rhubarb use has been linked to at least 24 cases of liver injury, although details on the dose of rhubarb and duration of use in these cases is unclear.

Likelihood Possible Evidence D
Nephrotoxic Drugs

Theoretically, long-term use of anthraquinones from rhubarb might increase the risk of nephrotoxicity when used with nephrotoxic drugs.
The anthraquinone constituents of rhubarb have been shown to induce nephrotoxicity in animal research. Additionally, in a case report, a 23-year old female presented with kidney failure after taking 6 tablets of a proprietary slimming agent (found to contain the anthraquinones emodin and aloe-emodin from rhubarb) daily for 6 weeks and then adding diclofenac 25 mg 4 times daily for 2 days. The authors postulate that the anthraquinone constituents of rhubarb contributed to the renal dysfunction, and the addition of diclofenac, a nephrotoxic drug, led to renal failure. Until more is known, advise patients to avoid taking rhubarb if they are taking other potentially nephrotoxic drugs.

Likelihood Possible Evidence D
Stimulant Laxatives

Theoretically, rhubarb might increase the risk for fluid and electrolyte loss when taken with other stimulant laxatives.
Rhubarb has stimulant laxative effects. Concomitant use with stimulant laxatives might compound fluid and electrolyte loss.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, excessive use of rhubarb might increase the risk of bleeding when taken with warfarin.
Rhubarb has stimulant laxative effects and can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Advise patients who take warfarin not to take excessive amounts of rhubarb.

Likelihood Possible Evidence D
Rheum palmatum full monograph & interactions

Bupleurum chinense3 drug types · 327 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, bupleurum might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research suggests that saikosaponins, constituents of bupleurum, can inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, bupleurum might decrease the effects of antidiabetes drugs.
Animal research suggests that saikosaponins, constituents of bupleurum, can increase blood glucose.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, bupleurum might decrease the effects of immunosuppressants.
In vitro and animal research suggests that bupleurum might stimulate immune function.

Artemisia capillaris2 drug types · 248 drugs

Cns Depressants

Theoretically, yin chen might enhance the therapeutic and adverse effects of other CNS depressants.
Animal research shows that yin chen has sedative effects and can reduce motor activity and impair balance and coordination. When used in combination with pentobarbital, yin chen increases sleeping time when compared to pentobarbital alone.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, yin chen might enhance the therapeutic and adverse effects of pentobarbital.
Animal research shows that yin chen, given orally in combination with pentobarbital, can increase sleeping time compared to pentobarbital alone.
